around 6:30 this morning, I started getting the following messages in my log: Feb 6 06:33:34 mojo postgres[1117]: [2-1] :: ERROR: could not access status of transaction 544441911 Feb 6 06:34:35 mojo postgres[1128]: [2-1] :: ERROR: could not access status of transaction 544441911 [...] repeated roughly once a minute. I've never seen this before. this is on postgres 8.1.1 running on fedora core 4 smp. I don't have any contextual information yet but I'm getting ready to turn statement logging on. Anybody know what this is? merlin
